GAMMA CORRECTING CIRCUIT AND PANEL DRIVE APPARATUS EQUIPPED WITH GAMMA CORRECTING CIRCUIT

摘要

gamma correction adjusts the gamma characteristic of each unit of the circuit is adjusted on the basis of the correction data , the primary voltage generating circuit selecting a reference voltage from the voltage generated in the primary , and also selects the gamma correction resistor circuit of the reference voltage output target reference voltage to be output from the reference voltage output terminal candidates . Since it is possible a double adjustment by the selection of the second phase in this way, it is possible to broaden the range of adjustment of the gamma correction characteristic .
